About NMEA 2000
®
Cables and Connectors
The NMEA 2000
®
standard goes beyond defining
message content and includes requirements
for the cabling used to interconnect electronic
components (referred to as the physical
interface). The following catalog pages contain
the NMEA 2000
®
approved network interconnect
components used to build an operational network.
About Micro, Mid and Mini Cable Systems
There are three types of NMEA 2000
®
cabling
systems, Micro, Mid and Mini. The Micro/
Mid cable system is generally used for smaller
networks requiring less power (i.e., less than 4
amps per network leg) while the Mini cable system
is used for larger networks (i.e., more than 4 amps
but less than 8 amps per leg).
